Unlocking Weight Gain Mysteries: Metabolism Matters
Have you ever wondered why some people gain weight despite eating little while others stay slim even when they indulge? This question has intrigued many, and Dr. Saurabh Sethi, a gastroenterologist with training from esteemed institutions like AIIMS and Stanford, sheds light on this phenomenon through his recent social media post.
Dr. Sethi emphasizes that metabolism is the key factor influencing weight gain, not just willpower or portion control. He explains that every individual has a different Basal Metabolic Rate (BMR), which is the energy the body expends to maintain basic functions like breathing, digestion, and circulation. Some are naturally endowed with a faster BMR due to genetic factors, thyroid function, hormonal balance, or increased muscle mass.
In his insights, Dr. Sethi points out that individuals with a slower BMR burn fewer calories, even when at rest. This means that even if they try to control their food intake, they may still struggle with weight gain. Moreover, people with lower muscle mass tend to have a lower calorie-burning capacity. This situation often arises after crash diets, prolonged calorie restrictions, or natural muscle loss with age.
Dr. Sethi elaborates on the importance of muscle mass in the weight management equation. Muscles burn significantly more calories than fat, even during rest—up to three to five times more. Therefore, having more muscle allows individuals to consume more calories without gaining weight, making regular physical activity essential.
Furthermore, hormonal imbalances, such as insulin resistance, can complicate this issue, making it easier for the body to store fat while hindering fat burning. This condition is commonly seen in individuals with fatty liver disease, polycystic ovary syndrome (PCOS), prediabetes, and diabetes.
Dr. Sethi concludes that the goal should not be merely to eat less. Instead, individuals should focus on optimizing their metabolism by building muscle, maintaining stable hormones, ensuring quality sleep, and engaging in consistent physical activity. By understanding and addressing these factors, anyone can improve their weight management and overall health.
